Problems solved by technology

These currents lead to a heating of the heating element.
In addition to heat generated by eddy currents, the alternating magnetic field may also cause the susceptor to heat due to the hysteresis mechanism.

Embodiment Construction

[0016]Changing the position of the housing portions with respect to each other from the first position in which the aerosol-generating device may be operated normally to the second position enables the heating element to be cleaned or replaced. The second position may enable an easy access to the heating element. Aerosol-forming substrate containing tobacco may be provided in the form of an aerosol-generating article. The aerosol-generating article may be provided as a consumable such as a tobacco stick. In the following, the aerosol-generating article will be denoted as a consumable. These consumables may have an elongate rod-like shape. Such a consumable is typically pushed into a recess of the device. In the recess, the heating element of the induction heater is provided such that the consumable is pushed over the heating element. In this way the heating element may penetrate the consumable. Once the aerosol-forming substrate in the consumable is depleted after multiple heating c...

Abstract

An aerosol-generating device is provided, including: an induction heater configured to heat an aerosol-forming substrate, the induction heater including an induction coil and a heating element, the heating element being arrangeable within the induction coil, and the induction coil having a varying pitch. An aerosol generating system is also provided, including the aerosol generating device and an aerosol generating article including an aerosol-forming substrate.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional application of and claims benefit under 35 U.S.C. § 120 to U.S. application Ser. No. 16 / 637,058, filed on Feb. 6, 2020, which is a U.S. national stage application of PCT / EP2018 / 071264, filed on Aug. 6, 2018, and claims benefit of priority under 35 U.S.C. § 119 to EP 17185563.8, filed on Aug. 9, 2017, the entire contents of each of which are incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to an aerosol-generating device comprising an induction heater for heating an aerosol-forming substrate. The induction heater comprises an induction coil and a heating element, wherein the heating element is arrangeable within the induction coil, such that it can be heated inductively.DESCRIPTION OF THE RELATED ART[0003]It is known to employ different types of heaters in aerosol-generating articles for generating an aerosol. Typically, resistance heaters are employed for heating an aeros...
